Example
DLLStructCreateDef("WindowPos", @" ptr hwnd; ptr hwndInsertAfter; int x; int y; int cx; int cy; uint flags "); // Create the MDI GUI $GUI = GUICreate("MDIWindow", "GUI", 800, 600); // Show the MDI GUI GUILoad( $GUI ); // Create the Design Window $Window = GUICreate("Window", "GUI", 640, 482, 0, 0); GUIMDIParent($Window, $GUI); // Show the Design Window GUILoad( $Window ); // Add a MsgFilter to Design Window GUIWndProc($Window, 'DesignWndProc($HWND, $MSG, $WPARAM, $LPARAM);'); // Keep the GUI running as long as long as the window is open While ( GUIStatus( $GUI ) ) DoEvents( ); Function DesignWndProc($HWND, $MSG, $WPARAM, $LPARAM) { if ($MSG == 0x0046) # WM_WINDOWPOSCHANGING { $Struct = PTRToDLLStruct("WindowPos", $LParam); DLLStructSetData($Struct, "x", 0); DLLStructSetData($Struct, "y", 0); } return 0; }
